Mechanical Control Shock-Absorbent Anti-Recoil Universal Mechanism

ABSTRACT

Mechanical control shock-absorbent anti-recoil universal mechanism intended for various fields such as industrial and civil constructions, machine building industry, robotics et cetera, its purpose being to protect against the impact forces, recoil forces or vibrations. The mechanical control shock-absorbent anti-recoil universal mechanism comprises a mobile holder X, a joint lever and spring mechanism Y and an end holder Z. The mechanical control shock-absorbent anti-recoil universal mechanism has the role of absorbing and a cancellation of the impact forces and recoil forces, while a mechanical control mechanism K adjust concomitently and continuously the tension of the absorbent springs and the annulling springs in order to decrease or to annul the impact force.

The invention refers to a mechanical control shock-absorbent anti-recoilmechanism, intended for industrial and civil constructions, machinebuilding industry, defense industry, robotics, etc., its purpose beingto protect against the impact forces, recoil forces or vibrations thatoccur in an instantaneous manner or under operation.

There are known shock-absorbent anti-recoil mechanisms that are equippedwith springs, telescopic means, hydraulic brakes, magnetic brakes etc.These mechanisms have the disadvantage that they do not provide neitheran universal applicability nor possibilities to adjust the effect of theimpact forces acting on construction, firearm etc., that occur in aninstantaneous or a controlled manner, under the action of the outerimpact forces, a recoil or vibrations.

There are also known anti-recoil mechanisms which are able to overtakethe recoil energy of the portable firearms. These mechanisms have alsothe disadvantage that they do not provide an universal applicability,while the component parts of the some assemblies or subassembliescomplicate their construction and increase the cost price of theproduct.

The technical problem that the invention solves consist in theachievement of a mechanical control shock-absorbent anti-recoiluniversal mechanism which has a simple construction, needs an easyaccess fabrication technology, ensures an universal use and an importanteffect of decreasing or even cancellation of the impact forces or of therecoil forces, so that the cancellation of said impact forces or recoilforces which occurs instantaneously or under controlled action beachieved in a continuous manner, according to the protection requirementthat is imposed on the operation of the construction, machine, equipmentor firearm.

The mechanical control shock-absorbent anti-recoil universal mechanismof the invention solves this technical problem and removes theup-mentioned disadvantages in that it comprises a mobile holder, a jointlever and spring mechanism, and an end holder that comprises amechanical adjustment mechanism. It comprises also joint spindles, ajoint gliding holder, a joint pin, locks, short levers, spring-seatjoint pins, absorption springs, a central joint pin, long levers, acancellation spring-seat pin, cancellation springs, a base holder, amechanical adjusting mechanism, a spacer, a fitting screw, a spring-seatscrew spindle, and holding screws. The above mentioned end holder has apilot case, in which it is introduced a mechanical adjusting mechanismcomprising a triple nut, a central screw, a joint pin, a mounting keyand a wear strip and an adjusting key.

The mechanical control shock-absorbent anti-recoil universal mechanismaccording to the invention has the following advantages:

-   -   it has an universal applicability;    -   it can be adjusted according to the impact or the recoil force,        so that the effects thereof is decreased;    -   it can be used in the field of the civil constructions,        industrial constructions, machine construction industry and        defense industry.

The mechanical control shock-absorbent anti-recoil universal mechanism

A (FIGS. 1-9) of the invention comprises a mobile holder X, that has therole of producing and transmitting the impact force or the recoil force,a joint lever and spring mechanism Y, that has the role of absorbing andcancellation of the impact forces or recoil forces, an end holder Z, anda mechanical adjusting mechanism K, that has the role to adjust theabsorbent and cancellation springs, concomitantly and continuously inaccordance with the shock-suppression anti-recoil requirement.

The mobile holder X (FIG. 2) comprises a joint spindle 1, a fasteningscrew and an joint gliding holder 3 which is jointly connected with themechanism Y by a joint spindle 4. In its turn, the joint lever andspring mechanism Y comprises two short levers 6,7 which are jointed atan end by means of said joint spindle 4, and two long levers 11,12 whichare jointed at an end to the central area of the short levers 6,7 bymeans of spring-seat joint pin 8, while at their central area areconnected by a central joint pin 10. The short levers 6,7 are providedat their other ends also with a spring joint pin, while the long levers11,12 are provided at their terminal areas with an spring-seat joint pin8, and at their ends they have a cancellation spring seat pin 13. To theends of said three spring-seat joint pins 8 are connected with theirends six absorbent springs 9, while to the ends of said two cancellationspring-seat pins are connected two cancellation springs 14. On thewhole, the joint lever and spring mechanism comprises six absorbentsprings and four cancellation spring.
